Reviews of cotton science and technology during 50 years and developming strategies in the early 21st century in Shandong Province

Since the founding of our People's republic,prominent achievements in cotton science and technology have been acquired in Shandong Province.At the cross of old and new century,many new problems in cotton production and study need to be overcome.In the early 21st century,cotton planting area in Shandong should be remained stable over 40×10 4hm 2,variety should be multi-style and regionalization,meanwhile,increasing yield per unit area and improving fiber quality should be done.The main study points in cotton are as follows:biotechnology,breeding of new cotton varieties including extra-high yielding varieties,hybrids and specialized fiber varieties;theories and techniques of extra-high yield cultivation;technique system of integrated pest management.
